The working principle of the invention is that when people want to detect the combustible gas, the combustible gas detection alarm device for processing the health food can be used, firstly, a user presses a power supply main switch to electrify the device, the user inserts a gas pipe 3 into a combustible gas pipeline, after the gas pipe 3 is inserted, the user inserts a water pipe into a spraying mechanism 7, after the water pipe is inserted, the user injects inert gas into an inert gas injection mechanism 8, when the concentration value of the floating dust in the environment of the combustible gas mixture leaked in the air reaches the preset value of a dust sensor 4, the control module controls the detector mechanism 5 to operate, meanwhile, the control module controls the spraying mechanism 7 to operate, the detector mechanism 5 makes a sound to remind the user, and the value of the concentration is displayed through the detector mechanism 5, clear water is sprayed on the gas pipe 3 through the spraying mechanism 7 to prevent fire caused by overhigh temperature of the gas pipe 3, when the sound sent by the detector mechanism 5 reaches the preset value of the closing mechanism 6, the control module controls the closing mechanism 6 to operate, the closing mechanism 6 closes the inside of the gas pipe 3 to prevent the combustible gas from flowing through the gas pipe 3, so that the combustible gas is limited, when the flow rate of the clear water reaches the preset value of the spraying mechanism 7, the control module controls the inert gas injection mechanism 8 to operate, the inert gas flows into the gas pipe 3 through the inert gas injection mechanism 8 to neutralize the residual combustible gas in the gas pipe 3, so that the upper explosion limit of the combustible gas is reduced, the combustible gas is prevented from being exploded when encountering open fire, the safety of the combustible gas is improved, when the concentration value of floating dust in the environment of the combustible gas mixture leaked in the air is smaller than the preset value of the dust sensor 4, make control module control detector mechanism 5 and spraying mechanism 7 stall, detector mechanism 5 stops to send out the sound, spraying mechanism 7 stops to spray the clear water, when the sound that detector mechanism 5 sent is less than closing mechanism 6's default, make control module control closing mechanism 6 stall, closing mechanism 6 opens inside gas pipe 3, thereby remove the restriction to the combustible gas, when the velocity of flow of clear water is less than spraying mechanism 7's default, make control module control inert gas injection mechanism 8 stall, inert gas injection mechanism 8 stops to extract inert gas, the user presses the power master switch once more afterwards, with this device outage.

When the concentration value of floating dust in the environment of the combustible gas mixture in the air reaches the preset value of the dust sensor 4, the control module controls the buzzer 55 to work, the buzzer 55 makes a sound to remind a user, and the numerical value of the concentration value of the floating dust in the environment of the combustible gas mixture is displayed through the LCD display screen 52, so that the user can conveniently observe the leakage condition of the combustible gas in time through the numerical value change displayed by the LCD display screen, when the concentration value of the floating dust in the environment of the combustible gas mixture in the air is smaller than the preset value of the dust sensor 4, the control module controls the buzzer 55 to stop working, and the buzzer 55 stops making a sound.

When the sound that sends buzzer 55 reaches sound sensor 63's default, make control module control solenoid valve 61 circular telegram, solenoid valve 61 closes inside gas pipe 3, make the combustible gas can't flow through gas pipe 3, thereby restrict the combustible gas, when the sound that sends buzzer 55 is less than sound sensor 63's default, make control module control solenoid valve 61 cut off the power supply, solenoid valve 61 opens inside gas pipe 3, thereby remove the restriction to the combustible gas, make combustible gas accessible gas pipe 3 flow.

The user inserts water pump 71 with the water pipe after, when the concentration value of the dust that floats in the environment of the combustible gas mixture in the air reaches dust sensor 4's default, make control module control water pump 71 work, water pump 71 extracts the clear water in the water pipe, make the clear water flow into in gondola water faucet 73 through water pump 71 and outlet pipe 72, the clear water rethread gondola water faucet 73 sprays on gas pipe 3, thereby cool down the air, spray on gas pipe 3 simultaneously, prevent that gas pipe 3 high temperature and conflagration from taking place, when the concentration value of the dust that floats in the environment of the combustible gas mixture in the air is less than dust sensor 4's default, make control module control water pump 71 stop work, water pump 71 stops to extract the clear water.

After the user pours into inert gas into and deposits trachea 83, when the clear water sprays through gondola water faucet 73, when the velocity of flow of clear water reaches water flow sensor 74's default, make control module control air pump 82 work, air pump 82 extracts inert gas, inert gas is through depositing trachea 83, air pump 82 and outlet duct 84 flow in gas pipe 3, make inert gas carry out the neutralization to remaining combustible gas in the gas pipe 3, thereby reduce combustible gas's explosion upper limit, when the velocity of flow of clear water is less than water flow sensor 74's default, make control module control air pump 82 stop work, air pump 82 stops to extract inert gas.

When the flow rate of the clean water reaches the preset value of the water flow sensor 74, the output shaft of the control module driving motor 92 is enabled to rotate forwards for two seconds, the output shaft of the driving motor 92 drives the connecting frame 93, the fixer 94, the water outlet pipe 72 and the shower head 73 to rotate forwards, the connecting frame 93 moves along the sliding rail 95, after two seconds, the output shaft of the control module driving motor 92 rotates backwards for two seconds, the output shaft of the driving motor 92 drives the connecting frame 93, the fixer 94, the water outlet pipe 72 and the shower head 73 to rotate backwards, the clean water is enabled to be uniformly sprayed in the air and on the gas pipe 3 through the front and back alternate movement of the shower head 73, the uniform cooling effect is achieved, when the flow rate of the clean water is smaller than the preset value of the water flow sensor 74, the control module controls the driving motor 92 to stop working, and the shower head 73 stops working therewith.

When the user wants to overhaul this equipment, the user rotates handrail 102 forward, handrail 102 drives open close board 101 and second hinge 105 and rotates forward, first spring 104 twists reverse deformation, open close board 101 rotates forward when the assigned position, user control handrail 102 stops, make open close board 101 open fixed frame 2 inside, the user can look over and overhaul this equipment, this overhaul of the equipments is accomplished the back, the user loosens handrail 102, first spring 104 resets, thereby drive handrail 102, open close board 101 and second hinge 105 rotate backward and resume the normal position, make open close board 101 close fixed frame 2 inside.
